Well i have a G-62 here that seems had a smoke system attached to it at some time. The crankcase has been tapped and a connectior for pressure line i would imagine for the pump to work. Is there anyway of plugging that up since i do not want to use a smoke system?

If the case is tapped just under the exhaust the thread is most likely a 1/4-28...You can get a SHORT bolt at the hardware store, use the washer from a glow plug, and stop up the hole...[8D]
Pressure in the crankcase is no more than 5 or 6 lbs, and is intermittent...Not nearly enough to dislodge anything....
